At 9:45 p.m. CDT on May 4, 2007, Greensburg was hit by an EF5 tornado. The tornado was estimated to be 1.7 miles in width and traveled for nearly 22 miles. Ninety-five percent of the city was confirmed to be destroyed, with the other five percent in severe damage. The National Weather Service estimated winds of the tornado to reach 205 mph. This was the first tornado to ever be rated EF5 since the update of the Fujita scale, and also is the first "5" classification since May 3, 1999, when an F5 tornado ripped through Moore, Oklahoma, as part of the Oklahoma Tornado Outbreak. As of May 8, 2007, eleven fatalities have been attributed to the tornado. Tornado sirens sounded in the city twenty minutes before the tornado struck, and a tornado emergency was issued, which undoubtedly saved many lives.
